Does Cisco ASA support OSPF?
Cisco ASA/PIX must run Version 7. x or later. OSPF is not supported in multi-context mode; it is supported only in single mode.
How do I connect to OSPF?
Configuring OSPF in a Single Area
- Use the command router ospf process ID to start OSPF.
- Use the network command to enable the interfaces.
- Identify area assignments.
- (Optional) Assign the router ID. Example 3-1 displays OSPF with a process ID of 1 and places all interfaces configured with an IP address in area 0.
Which is OSPF protocol does Cisco routers support?
OSPF also allows packet authentication and uses IP multicast when sending and receiving packets. Cisco supports RFC 1253, OSPF Version 2 Management Information Base, August 1991. The OSPF MIB defines an IP routing protocol that provides management information related to OSPF and is supported by Cisco routers.
How does the Cisco IP OSPF cost interface work?
On any point-to-multipoint interface (broadcast or not), the Cisco IOS software assumed that the cost to each neighbor was equal. The cost was configured with the ip ospf cost interface configuration command. In reality, the bandwidth to each neighbor is different, so the cost should differ.
Can you configure OSPF as a broadcast network?
OSPF Network Type. You have the choice of configuring your OSPF network type as either broadcast or NBMA, regardless of the default media type. Using this feature, you can configure broadcast networks as NBMA networks when, for example, you have routers in your network that do not support multicast addressing.
What are the different administrative distances in OSPF?
OSPF uses three different administrative distances: intra-area, interarea, and external. Routes within an area are intra-area; routes to another area are interarea; and routes from another routing domain learned via redistribution are external. The default distance for each type of route is 110.
